What type of sound do you have on mind? Could you give us some examples here. I can see that Soundcloud clip you posted here is yours, so i'm guessing that's the project you've been trying to get proper sound for, am i right?

It is hard to get exactly that sound using only Phoscyon. I tried to recreate it using Devastor and Syntorus... yes - chorus. I think that i nailed the sound quite good.
Below you can find attached picture with knobs setup - i assume that you have your own riff.
You can also lower the resonance to get more "dark" acid
